Looks like a cheap caulk of some kind. Yes remove all of it that you can. Then follow directions on the Dycor rubber sealant and reseal it all. We've had good luck with the Dycor. It cannot be used around
windows as it runs that is why it is used on the roof area. Clean the area around the small holes and put some over them. Dycor is quite thin compared to other caulk and will flatten out so clean the area for a ways around the small holes. I've never seen Dycor crack like that as it is rubber and rubber doesn't crack open. For anyone that has a rubber roof check to make sure the sealant you get can be used on the rubber roof.
